And allocating resources for the target logic channel.

Here, optionally, the step may specifically include the steps of:

The following describes the implementation of the resource allocation method according to the present invention in detail with reference to four examples.

Example one

In this example, the resource allocation method specifically includes the following steps:

step a1: the terminal determines a mapping relationship between the logical channels and the logical channel priority limit parameters.

Here, the mapping relationship between the logical channels and the logical channel priority restriction parameters is determined by the terminal itself.

or determining, by the terminal MAC layer or RRC layer, a mapping relationship between the logical channels and the logical channel priority limit parameters based on the higher layer indication information;

Here, LCP parameters include, but are not limited to, at least one of the following:

direct communication interface wireless access technology based on 5G NR.

Here, the resource types include: unicast resources, multicast resources, and broadcast resources; or, a set of unicast resources and multicast resources, and broadcast resources; or a set of unicast resources and multicast and broadcast resources.

Step b1: the terminal determines a scheduling grant corresponding to the direct communication interface.

Here, for the self-selected resource allocation mode of the terminal, the terminal may directly select a resource from the resource pool corresponding to the direct communication interface, and use the selected resource as the scheduling grant corresponding to the direct communication interface.

For the scheduled resource allocation mode, the terminal may allocate, by the resource allocation management node (network side device or group header), a scheduling grant corresponding to the direct communication interface to the terminal.

Step c1: and executing LCP process aiming at the scheduling permission corresponding to the direct communication interface, and organizing the MAC PDU of the direct communication interface.

Here, for the scheduling grant corresponding to each direct communication interface, resource allocation may be performed as follows:

step c11: for a scheduling grant corresponding to a direct communication interface, a logical channel of the direct communication interface that can use the scheduling grant is selected according to the LCP parameters of the logical channel.

Here, first, a logical channel in which data transmission is required in the direct terminal interface is determined.

Then, a logical channel that can use the scheduling grant is determined from among logical channels having data transmission requirements.

It should be noted that the logical channel for which the scheduling grant can be used needs to satisfy all LCP restrictions corresponding to the logical channel.

Here, the specific implementation process that the logical channel of the scheduling grant needs to satisfy all LCP reservations restrictions corresponding to the logical channel may be referred to in the above optional implementation, and the description of the specific implementation step portion of step 102 is not repeated here.

Step c12: and determining a target logical channel meeting preset conditions from logical channels of the direct communication interface which can use the scheduling permissions according to the scheduling permissions corresponding to the direct communication interfaces.

Here, specifically, from the logical channels of the direct communication interface that can use the scheduling grant determined in step c11, the logical channel with the highest priority is selected; determining a target identifier corresponding to a logic channel with the highest priority; and determining a logical channel corresponding to the target identifier from the logical channels of the direct communication interface which can use the scheduling grant as a target logical channel.

It should be noted that, each logical channel corresponds to one identifier, and identifiers corresponding to different logical channels may be the same or different.

Here, at least one logical channel having the highest priority is determined from among the logical channels of the direct communication interface that can use the scheduling grant.

When the number of the logic channels with the highest priority is greater than or equal to two, and different identifiers exist in the respective corresponding identifiers, the terminal can select one of the identifiers as the target identifier.

Step c13: resource allocation is performed for the target logical channel.

Here, specifically, the target logical channels are sequentially allocated with resources according to descending order of priority. Until the resources are exhausted, or the data of all logical channels corresponding to the target identification are allocated with the resources.

Example two

step a2: the terminal obtains the mapping relation between the logic channel configured by the resource allocation management node and the logic channel priority limit parameter.

Here, the mapping relationship between the logical channels and the logical channel priority restriction parameters is completely determined by the resource allocation management node (network side device or group header).

Specifically, the mapping relationship between the direct configuration logic channel and the logic channel priority limit parameter by the resource allocation management node may specifically include:

the terminal reports the logic channel of each direct communication interface and the wireless access technology and/or the resource type corresponding to the logic channel of each direct communication interface to the resource allocation management node;

or the terminal reports the logic channel of each direct communication interface and the QoS parameter corresponding to the logic channel of each direct communication interface to the resource allocation management node;

And finally, the terminal acquires the mapping relation between the logic channel configured by the resource allocation management node and the logic channel priority limit parameter.

Step b2: the terminal determines a scheduling grant corresponding to the direct communication interface.

Step c2: and executing LCP process aiming at the scheduling permission corresponding to the direct communication interface, and organizing the MAC PDU of the direct communication interface.

The specific implementation process of the step b2 and the step c2 may refer to example one, and will not be described herein.

Example three
